>>5252375Blender 2.7 unfolds the same shape just fine with and without applying scale and rotation. In 2.4 on the other hand, everything that could go wrong did.
I'm starting to think that the older algorhythm has trouble calculating islands with more than a few polies.
But thanks for helping regardless. I learned something. Btw, do you know if I can disable the automatic scaling and rotation of islands Blender does when it unwraps?
